梁孝王刘武 / Liu Wu, King Xiao of Liang (Western Han)

Overview

梁孝王刘武 / Liu Wu is a Western Han vassal king, son of Empress Dowager Dou and younger full brother of 汉景帝, whose resistance during the Rebellion of the Seven States becomes inherited political credit in the later punishment of his son 刘彭离.

Current Profile

The current source introduces Liu Wu only as the family and merit background to the Jidong case. It credits his Liang forces with resisting the rebels for more than three months during the Rebellion of the Seven States, buying time for the central court’s counterattack. That remembered service matters beyond his own life: when officials request Liu Pengli’s execution for more than one hundred known killings, the episode treats Liu Wu’s contribution, together with royal kinship, as part of 汉武帝’s reason for choosing deposition and exile instead.

The profile therefore does not yet attempt a complete biography. Its current contribution is narrower: exceptional service by one royal actor can become inherited clemency capital for a descendant, even when the descendant’s conduct is unrelated and extremely grave.

Key Characteristics

• Son of Empress Dowager Dou and younger full brother of Han Jingdi.
• Western Han ruler of Liang during the Rebellion of the Seven States.
• Credited by the episode with holding out against rebel forces for more than three months.
• Presented as buying time for the central counterattack.
• Father of Liu Pengli, king of Jidong.
• His remembered service becomes part of the later argument for sparing his son from execution.

Evidence

Royal identity and rebellion-era service:

• Hanji 338-1 identifies Liu Wu as Han Jingdi’s younger full brother and credits Liang’s resistance with supporting the suppression of the Rebellion of the Seven States.

Inherited political credit:

• Hanji 338-1 invokes Liu Wu’s service when explaining why Han Wudi does not execute Liu Pengli despite the officials’ request.

Qualifications

This profile currently rests on one short episode whose purpose is Liu Pengli’s criminal case, not Liu Wu’s full career. The precise siege, duration, military contribution, succession position, Liang court, and broader relationship with Han Jingdi are outside the supplied source. The episode’s causal link between the father’s merit and the son’s clemency is an interpretation of Wudi’s refusal to execute, not a surviving formal judgment quoted in full.

What Changed

• Created a bounded profile centered on rebellion-era service and its later use as inherited clemency capital.

Relationships

• 汉景帝 - elder full brother and emperor whose throne Liu Wu’s resistance helps defend.
• 济东王刘彭离 - son whose requested execution is mitigated in part through the father’s remembered service.
• 汉武帝 - nephew who later decides Liu Pengli’s punishment.
• 宗室亲缘减刑 - pattern through which Liu Wu’s merit is presented as benefiting his son.
• 西汉 - dynastic setting for Liang’s rebellion-era defense and the later Jidong case.
